Certificateholders of the Schedule K-1s necessary to enable each

opinion, no less favorable to the Issuer than would be available from Persons
that are not Affiliates of the Administrator.

                  (vii) The Administrator shall indemnify, defend and hold
harmless the Indenture Trustee and the Owner Trustee from and against any and
all costs, expenses, losses, claims, damages, and liabilities to the extent that
such cost, expense, loss, claim, damage, or liability arose out of, or was
imposed upon the Indenture Trustee or the Owner Trustee through the negligence,
willful misfeasance or bad faith of the Administrator in the performance of its
duties under this Agreement or by reason of reckless disregard of its
obligations and duties under this Agreement. Indemnification under this Section
2(b)(vii) shall include, without limitation, reasonable fees and expenses of
counsel and expenses of litigation. If the Administrator has made any indemnity
payments pursuant to this Section 2(b)(vii) and the recipient thereafter
collects any of such amounts from others, the recipient shall promptly repay
such amounts collected to the Administrator, without interest.

direction. For the purpose of the preceding sentence, "non-ministerial matters"
shall include, without limitation:

the manner in which it accomplishes the performance of its obligations
hereunder. Unless expressly authorized by the Issuer, the Administrator shall
have no authority to act for or represent the Issuer or the Owner Trustee in any
way and shall not otherwise be deemed an agent of the Issuer or the Owner
Trustee.

                  8. No Joint Venture. Nothing contained in this Agreement (i)

unincorporated business or other separate entity, (ii) shall be construed to
impose any liability as such on any of them or (iii) shall be deemed to confer

acting in a similar capacity as an administrator for any other person or entity
even though such person or entity may engage in business activities similar to
those of the Issuer, the Owner Trustee or the Indenture Trustee.

to the Issuer, the Administrator or the Indenture Trustee under this Agreement
shall be delivered as specified in Appendix B of the Trust Sale and Servicing

                  13. Amendments.

         (a) This Agreement may be amended from time to time with prior notice
to the Rating Agencies by a written amendment duly executed and delivered by the
Issuer, the Administrator and the Indenture Trustee, with the written consent of
the Owner Trustee, without the consent of the Financial Parties, for any of the
following purposes:

                  (i) to add provisions hereof for the benefit of the
Noteholders and Certificateholders or to surrender any right or power herein
conferred upon the Administrator;

                  (ii) to cure any ambiguity or to correct or supplement any
provision herein which may be inconsistent with any other provision herein;

                  (iii) to evidence and provide for the appointment of a
successor Administrator hereunder and to add to or change any of the provisions
of this Agreement as shall be necessary to facilitate such succession; and

                  (iv) to add any provisions to or change in any manner or
eliminate any of the provisions of this Agreement or to modify in any manner the
rights of the Noteholders or Certificateholders; provided, however, that such
amendment under this Section 13(a)(iv) shall not, as evidenced by an Opinion of
Counsel, materially and adversely affect in any material respect the interest of
any Noteholder or Certificateholder.

         (b) This Agreement may also be amended by the Issuer, the Administrator
and the Indenture Trustee with prior notice to the Rating Agencies and with the
written consent of the Owner Trustee and the holders of Notes evidencing at
least a majority in the Outstanding Amount of the Notes as of the close of the
immediately preceding Distribution Date and the holders of Certificates
evidencing at least a majority of the Voting Interests as of the close of the
preceding Distribution Date for the purpose of adding any provisions to,
changing in any manner or eliminating any of the provisions of this Agreement or
of modifying in any manner the rights of Noteholders or the Certificateholders;
provided, however, that no such amendment may (i) increase or reduce in any
manner the amount of, or accelerate or delay the timing of, collections of
payments on Receivables or distributions that are required to be made for the
benefit of the


                                       10
<PAGE>


Noteholders or Certificateholders, (ii) reduce the percentage of the holders of
Notes and Certificates which are required to consent to any amendment of this
Agreement or (iii) modify or alter any provision of this Section 13, except to
provide that certain additional provisions of this Agreement and the Basic
Documents cannot be modified or waived without the consent of each Noteholder
and Certificateholder affected thereby, without, in any such case, the consent
of the holders of all the outstanding Notes and Certificates.

         (c) Notwithstanding Sections 13(a) and 13(b), the Administrator may not
amend this Agreement without the permission of the Seller, which permission
shall not be unreasonably withheld.

                  14. Successors and Assigns. This Agreement may not be assigned
by the Administrator unless such assignment is previously consented to in
writing by the Issuer and the Owner Trustee and subject to the satisfaction of
the Rating Agency Condition in respect thereof. An assignment with such consent
and satisfaction, if accepted by the assignee, shall bind the assignee hereunder
in the same manner as the Administrator is bound hereunder. Notwithstanding the
foregoing, this Agreement may be assigned by the Administrator without the
consent of the Issuer or the Owner Trustee to a corporation or other
organization that is a successor (by merger, consolidation or purchase of
assets) to the Administrator, provided that such successor organization executes
and delivers to the Issuer, the Owner Trustee and the Indenture Trustee an
agreement in which such corporation or other organization agrees to be bound
hereunder by the terms of such assignment in the same manner as the
Administrator is bound hereunder. Subject to the foregoing, this Agreement shall
bind any successors or assigns of the parties hereto.

                  15. Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK, WITHOUT
REGARD TO THE PRINCIPLES OF CONFLICTS OF LAWS THEREOF OR OF ANY OTHER
JURISDICTION OTHER THAN SECTION 5-1401 OF THE NEW YORK GENERAL OBLIGATIONS LAW,
AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES UNDER THIS AGREEMENT
SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

                  16. Headings. The section headings hereof have been inserted
for convenience of reference only and shall not define or limit any of the terms
or provisions hereof.

                  17. Separate Counterparts. This Agreement may be executed by
the parties in separate counterparts, each of which when so executed and
delivered shall be an original, but all such counterparts shall together
constitute but one and the same instrument.

                  18. Severability of Provisions. If any one or more of the
covenants, agreements, provisions or terms of this Agreement shall for any
reason whatsoever be held invalid, then such covenants, agreements, provisions
or terms shall be deemed severable from the remaining covenants, agreements,
provisions or terms of this Agreement and shall in no way affect the validity or
enforceability of the other provisions of this Agreement or of the Certificates
or the rights of the holders thereof.

warranties, covenants, agreements or other obligations of the Issuer hereunder

all purposes of this Agreement, in the performance of any duties or obligations
of the Issuer hereunder, the Owner Trustee shall be subject to, and entitled to
the benefits of, the terms and provisions of Article VI of the Trust Agreement.

event shall JPMorgan Chase Bank, N.A. have any liability for the
representations, warranties, covenants, agreements or other obligations of the
Issuer hereunder or in any of the certificates, notices or agreements delivered
pursuant hereto, as to all of which recourse shall be had solely to the assets
of the Issuer. For all purposes of this Agreement, in the performance of any
duties or obligations of the Issuer hereunder, the Indenture Trustee shall be
subject to, and entitled to the benefits of, the terms and provisions of Article
VI of the Indenture.

                  21. Third-Party Beneficiary. The Owner Trustee is a
third-party beneficiary to this Agreement and is entitled to the rights and
benefits hereunder and may enforce the provisions hereof as if it were a party
hereto.
